`To 1r/ZZ whom 'lit may concern.'

and HARRY C. HAAK, citizensot the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful AImprovements in \Vashing-Machines; and we do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in washing-machines, and particularly to that class of machines which are provided with means whereby hydraulic, pneumatic, or other pressures may beemployed for operating the machine.

claimed.

In the accompanying drawings, Figure 1 is a vertical central section through a washinginachine embodying our invention. Fig. 2 is a plan view o1 a part oi the tub, showing the iioat within the same and the bottom of the tub. Fig'. 3 is a detail cross-sectional View through the central post oi the washing-machine- Fig. 4 is a detail View illustrating the latch employed :tor preventing the said post from becoming loosened during the operation of the machine. Fig. 5 is a detail perspective view showing the locking means 'for holding the tub stationary. Fig. 6 isadetail Avertical sectional view through a portion of the washing-ma? chine, showing a diul'erent means for connecting the pressure-cylinder with the tub.

The washing-machine which is the subject of the present invention is adapted to be moved upon a pivot-pin back and forth, lirst in one direction and then in the other, the movements in the opposite direction being taken in quick` succession, so as to cause a rubbing action between the clothing or other articles placed in the tub and the inner surfaces of the tub, the bottom, and the iioat arranged therein. The tub is also so mounted that it may be connected with a pressure-cylinder so as to be rotated back and forth automatically by power. In carrying out these features ot' the invention we i'orm the machine with a main receptacle or tub 1, which is pivotally mounted upon a suitable support or base, as 2. The tub is provided with a removable pivot-pin, as 3, which projects downwardly through an elongated bearing 1, which is secured to the top of the base 2. The bearing 1 1 is preferably formed integral with a casting 5, which surrounds the upper ends or' the legs 6 6 thereol". The upper end of the pivot-pin 3 is screw-threaded and engages threads in a boss 7, formed on the spider 8, which is secured to the under side oi" the tubbottom, the said screw-threaded portion ot' the said pivot-pin also extending through lthe bottom ot' the tub and engaging a central post 9,

arranged within the tub. The lower end of the boss 7 is Jformed with a bearingsur't'ace adapted to engage a bearing, preferably a ball-beari ng, as 10, arranged in an annular recess 11, formed in the central portion of the casting The recess 11 is provided with a suitable bearinglining upon which the balls ot the bearing run. The tub will thus rest upon the base 2 on the antifrictionball-bearing thus formed.

Interiorly oi' the hub and on the bottom thereof is centrally arranged a disk or raised portion 12, the said raised portion being provided with a recess, as 13, in which is secured a plate or disk 14, which is secured to the bottom of the tub surrounding the pivot-pin. The plate lasurrounds the screw-thr`eaded end of the pivot-pin 3, upon which it isscrewed, and is formed at its center and on its upper face with a series oi" upwardly extending ratchet-teeth, as 15, which are adapted to be engaged by a latch 16, carried by the post The lower end of the latch is so shaped as te engage the teeth of the said ratchet when the post 9 is screwed down upon the upper end of the pivot-pin 3 and will prevent the said post from being' unscrewed 'from its position when the tub is being used. The latch 16 is prei'- erably clamped in its lowered position by means of a clamp-screw 17, which passes through a slot 18, 'formed in the shank ot' the latch 16. The said latch 1G is preferably arranged in a vertical groove or kerf, as 19, formed in the side of the post 9. A metallic cap or ferrule 2O preferably incloses the lower end of the post 9 and is provided with a threaded aperture to engage the threads on the end of the pivot-pin 3. A movable float or plate 21 is arranged upon the post 9, being movably connected therewith, so that it will rest by gravity upon the clothing or other articles to be washed in thev tub. In order to prevent this float from having a movement independent of the post 9, it is provided with a collar 22, which surrounds the post 9 and is formed with an inwardly-extending rib or key 23, which extends into the kerf 19 of the said post, so that the float will be turned in correspondence with the movement of the tub and post or will be free to slip up and down on the said post. A cover 24 is placed upon the top of the tub, so as to completely close the upper end thereof. The inner peripheral surface of the tub is formed with a series of corrugations 25, preferably vertically arranged, while the upper surface of the bottom is formed with radially-extending ribs or slats, as at 26. The under side of the iioat 2l is also provided with radially-arranged ribs or slats, as at 28, for engaging the materials in the tub, and the said lioat is further provided with a series of apertures 29, so that liquids may pass th rough the same from one side of the lioat to the other. The bottom of the tub is preferably provided with a drain-opening or outlet-aperture, as 30, which is controlled by a plug, as 3l. The opening is made fiaring'inshape and the plug formed to fit it. The plug 3l is provided with a stem 32, which extends downwardly through the opening 30 and is bent to one side to form a hook 38. When the plug is lifted, the hook may be brought into engagement with a hook 34 on the bottom of the tub, so as to hold the said plug in its raised position for draining the tub. The pivot-pin 3 is held in its bearing by a suitable nut, as 35, applied to the lower end of the said pin, but not screwed up against the end of the bearing, so as to prevent the free movement of the pin in rotation.

The tub may be locked in a stationary position when desired by means of a latch-lever, as 63, which is pivoted to the base 2 and is adapted to engage at its upper end a pair of lugs 64, secured to the spider 8 or the bottom of the tub. The lower end of the latchlever 63 extends downwardly a suitable disstance and is provided with means for engaging the rack or notched plate 65, secured to the said base. The lever may be moved along this rack, so that it will be brought into or out of engagement with the lugs 64 on the bottom of the tub.

In operating the tub the materials to vbe washed are placed in the body of the tub upon the bottom. Vater and other washing materials may then be placed in the tub, after which the iioat 2l is put in position on the post 9, so that it will rest upon the top of the clothes or other materials in the tub. The cover is then put in position, and the tub may be then unlocked by releasing the lugs 64 from the latch -lever 63. The tub is then turned by any suitable means back and forth upon its pivot. rlhe clothing or other materials inthe tub will gain momentum in the direction of the movement of the tub, and when the tub is stopped at the end of one motion the momentum will tend to carry the clothes farther around in the tub, especially as the tub is immediately started on its reverse movement. It will thus occur that at each end of the stroke of the tub the clothes will be more or less rubbed between the iioat and bottom and against the sides of the tub. The tub, float, and bottom, as well as the post 9, are all preferably formed of wood, so that there need be practically no metal contact with the clothing or other materials washed. After the washing operation has been completed the tub may again be locked in a stationary position by means of the latch-lever 63, and the liquids in the tub can be discharged through .the opening 30. f

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent, ism
